How to manage lupus nephritis in my 31-year-old sister?

Question

Hello doctor,

I am very scared about my 31-year-old sister, who was recently diagnosed with lupus nephritis after her kidney function started declining rapidly. Her creatinine level increased from normal to 2.4 within just three months, and she has protein in her urine measuring 3.8 grams per day, which the nephrologist explained is very high.

She was first diagnosed with lupus two years ago when she developed joint pain and a butterfly-shaped rash on her face, but we never expected it to affect her kidneys. The kidney biopsy showed class IV lupus nephritis with significant inflammation and some scarring already present.

She has been started on Prednisone 60 mg daily along with Mycophenolate, but she is experiencing severe side effects, including mood swings and difficulty sleeping. Her blood pressure has also become high at 155/95, even though she never had blood pressure issues before.

The most distressing part is that she got married six months ago, and they were planning to start trying for a baby. However, the medications used to treat lupus nephritis are not safe during pregnancy. Is it possible for her to have children in the future with this condition? We are also very worried about the possibility of dialysis, as our grandfather had kidney failure.

Kindly advise.

Hello,

Welcome to icliniq.com.

I understand your concern.

I am very sorry that your family is going through this, and it is completely natural to feel frightened when something this serious develops so quickly, especially after a joyful life event such as her marriage.

Lupus nephritis, particularly Class IV (diffuse proliferative lupus nephritis), is one of the more aggressive forms of kidney involvement, so the fear being felt is understandable. However, it is important to know that many individuals respond well to treatment, even when kidney involvement appears severe at the beginning.

The rise in creatinine levels and the heavy protein loss in the urine indicate active kidney inflammation. This is the reason her doctors started prompt and aggressive treatment with high-dose Prednisone and Mycophenolate mofetil.

Early and appropriate treatment offers the best chance to preserve kidney function and reduce the risk of progression to kidney failure. The side effects she is experiencing from steroids, such as mood changes, insomnia, and newly developed high blood pressure, are unfortunately common but often temporary.

Doctors usually aim to gradually reduce the steroid dose once the disease activity is better controlled. Managing blood pressure effectively is also a crucial part of protecting kidney function and can significantly improve long-term outcomes.

Regarding pregnancy, many women with lupus nephritis can have children, but careful timing is essential. Specialists usually recommend waiting until the disease is well-controlled and stable for at least six to twelve months. Once remission is achieved, there are treatment options that are considered safer during pregnancy and can be used under close medical supervision.

At present, the main priority is to control kidney inflammation and protect kidney function so that more options remain available in the future. Although this diagnosis can feel overwhelming and unfair, it does not automatically mean dialysis or the end of plans for motherhood. With coordinated care from nephrology and rheumatology specialists, regular monitoring, and emotional support, there is still realistic hope for stability and a meaningful future.
